DIGITAL VORTEX-GENIE®2 Mixer. Review instruction 3.0 before attempting to
change attachments.

To initiate the "FT" mode, press the MODE button until MIN is illuminated above the
START/STOP text. Next, press the UP/DOWN arrow buttons beneath the TIME
window to set the desired mixing time. Next, set the speed control by pressing the
UP/DOWN arrow buttons beneath the SPEED window. Press the START/STOP
button to begin the mixing action. The mixer will run until the set time has elapsed. To
stop the cycle before the set time has elapsed, press the START/STOP button. To
initiate a new timed cycle, press the START/STOP button again.

2.4 - "FC" (HANDS FREE CONTINUOUS)
The "FC" mode allows for unattended operation that will continue indefinitely until you
stop the cycle by pressing the START/STOP button. In this mode, you may also use
any of the accessory attachments available for the DIGITAL VORTEX-GENIE 2 Mixer.

To initiate the "FC" mode, press the MODE button until MIN is illuminated above the
START/STOP text. Next, press the DOWN arrow beneath the TIME window until the
illuminated display reaches "0". Upon releasing the button, the display will have two
dash marks (--), indicating that no time limit is set. Next, set the speed control by
pressing the UP/DOWN arrow buttons beneath the SPEED window. Upon pressing
the START/STOP button, the mixer will start and continue to run, unattended, until
you once again press the START/STOP button. To restart the cycle, press the
START/STOP button again.

2.5 - "SLEEP"
The mixer will automatically go into a "SLEEP" mode if the mixer is plugged in but not
used for 10 minutes. The TIME and SPEED illuminated displays will go blank and the
SEC or MIN illuminated display will blink. Press the START/STOP button to "WAKE
UP" the mixer.

Note: The speed control can be adjusted up or down during the mixing cycle,

however, the TIME can only be adjusted before the cycle begins.

3.0 - To change accessory mixing attachments, the following sequence is to be followed
explicitly.

3.1 - Turn the power OFF by unplugging the unit from the outlet.

3.2 - Grasp the installed attachment and pull straight up until it releases from the shaft. A
technique of lifting the attachment with your finger tips while using your knuckles as a
fulcrum will give you the leverage to remove the installed attachment component
smoothly.

3.3 - Hold the part you wish to install so the "flat" part of the shaft is aligned with the "flat"
of the receptacle in the attachment component. Alternatively, you may place the
attachment component on the shaft and turn it until you feel the "flats" aligning.

3.4 - Press attachment component firmly downward until it "snaps" into place. The
DIGITAL VORTEX-GENIE 2 Mixer is now ready to use with the newly installed
accessory attachment. Plug the unit back into the electrical outlet. Follow instructions

1.0 through 2.5 for proper use of the mixer.

Note: When installing the Microplate Adaptor press firmly down on the areas

indicated on the adaptor base. DO NOT press down on sidewalls as this may
bend the attachment.

4.0 - With prolonged use, your DIGITAL VORTEX-GENIE 2 Mixer may become warm to
the touch. It should not get HOT to the touch. The motor will radiate a certain amount
of heat that will be dissipated by the cast zinc case.

OPERATING INSTRUCTIONS

1.0 - Plug the line cord into a properly grounded electrical outlet.

(120 VAC for the SI-A536 model; 230 VAC for the SI-A546 model; 100 VAC for
the SI-A586 model). Illuminated numbers will appear in the TIME and SPEED

windows indicating that the unit is ON and ready for use.

2.0 - The DIGITAL VORTEX-GENIE 2 Mixer has the following modes of operation:

2.1 - "TT" (TIMED TOUCH - 1 to 99 seconds)

This mode can only be used with the optional 3-inch Platform or Pop-off Cup.

For procedures that require short duration vortex mixing from 1 to 99 seconds.
Or, for procedures that require accurate and repetitive vortex mixing sequences
of 1 to 99 seconds each.

To initiate the "TT" mode, press the MODE button until SEC is illuminated beneath the

the desired mixing time. Next, set the speed control by pressing the UP/DOWN arrow
buttons beneath the SPEED window. When you touch a tube or other vessel to the
3-inch Platform or Pop-off Cup, the mixer will start and run for 1 to 99 seconds,
depending on the TIME setting. The mixer will automatically turn off at the end of the
1 to 99 second cycle. Releasing the pressure on the 3-inch Platform or Pop-off Cup
and then re-applying the pressure will initiate another 1 to 99 second cycle. The
mixing cycles will be precisely timed and you may initiate as many mixing cycles as
you wish.

2.2 - "CT" (CONTINUOUS TOUCH)

This mode can only be used with the optional 3-inch Platform or Pop-off Cup.

The "CT" mode allows for operation that will continue indefinitely until you release
